This will be a dedicated theater with acoustical treatments. I do have some limitations though.

1) limited space behind the false wall. 15" would be extremely tight and am thinking speakers no deeper than 14" for LCR. (Subs not a problem - they will be elsewhere in the room).2) Need in walls for the surrounds (do to slope ceilings and room width)

Total room volume is approximately 2400 cuft and 7.2 system with bass shakers.

My system thoughts:M50 floor standing for LR (the only ones that will fit depth issue)VP150 center4X M3 in walls for surround2X EP350 Subs

Looking for overall thoughts on how this would work with the room. Is anything undersized/oversized in this configuration? Any advice really.

I think that you would see a big boost in front stage performance if you could get a set of M60 fronts instead of the M50s. Maybe look at the "in-cabinet" model since the port is in the front instead of the back meaning that they wouldn't take up as much space as the regular model, but even then you are still .31" too deep. A quandary for sure.

As for surrounds, if you are looking at a greater percentage of movies vs music listening, you will be blown away with the QS series surrounds. They are so good that you will find people that own front speakers from other manufacturers and come to Axiom for their surround speakers.

I plan on purchasing M50v3 to replace my M22's on stands, maybe sometime next year. The M22's on stands will then be moved up on the wall and replace my black on-wall M22's. I'm just going to stick with the standard cherry finish, so everything will one day match again.

I remember a review by one of our forum regulars (forget who now) that showed a marginal improvement of m60+m22 versus the m80. I don't think anyone has tried the m50+m22 combo you are suggesting so youll be the first.

Once you're sufficiently reproducing the required amounts of bass, midrange and treble (i.e., flat frequency response), what does adding more speakers (coming from the same direction) offer except messed up imaging?
